[R-gui] R-wxPython and dynamic linking issues

[James Wettenhall]

Hi,

I've mentioned before that when trying to run R-wxPython in 
Linux, you very quickly run up against some nasty dynamic 
linking issues, where RSPython can't find certain Python symbols 
in the wxPython shared libraries, so I had to rebuild wxPython 
linking against a Python shared library libpython2.2.so.

But then if you want to use shared libraries distributed with 
Python, such as parser.so, you need to be aware that they are 
not linked against a libpython2.2.so by default either, so it is 
possible to get undefined Python symbols there as well.

One workaround I am investigating is linking RSPython with:

-Wl,-whole-archive -lpython -Wl,-no-whole-archive

But I can't give R-wxPython much time this week, so I'd be happy 
if anyone else wants to start playing around with this idea 
before I do.

Regards,
James
